BACKGROUND Technical Field

The present disclosure relates to an information processing system, an information processing apparatus, and a method of generating screen.

Description of the Related Art

A configuration is known in which application software that operates on an image forming apparatus is developed as a web application software (referred to as a “web application” hereinafter).

For example, a technique is known in which an image forming apparatus displays a screen on a control panel of the image forming apparatus based on Hyper Text Markup Language (HTML) data provided by application software of an external server. This technique enables the development or management of application software at the external server, thereby improving efficiency of screen development.

Setting items and setting values that are set on an application screen sometimes vary depending on types of the web application that operates on the image forming apparatus. For this reason, developers of web applications have to develop, in addition to the web applications themselves, application setting screens for configuring setting values of setting items of the web applications. This degrades efficiency in developing web applications.

The “id” is a character string identifying “field”. The “label” is a title of a setting item displayed on the application setting screen.

The “type” indicates a type of setting items. As illustrated in FIG. 8B, examples of the type of setting items include a one-line text, a drop-down list, a multiple-line text, a radio button, and a check box. The “items” is used in a case in which “type” is any one of the drop-down list, the radio button and the check box, for example. In an example of FIG. 8B, options are indicated by “value” and “label”. The “value” indicates a value of each option and is a value set to the application setting value. The “label” is a label of each option displayed on the application setting screen.

FIG. 9 is an illustration of an example configuration of an application setting value. As illustrated in FIG. 9, an application setting value is associated with “id” of a setting item. For example, in FIG. 9, “default_filename”, which is “id” of a setting item, is associated with “(QUOTE)”, which is an application setting value. Further, “date_format”, which is “id” of a setting item, is associated with “yyyy-mm-dddd”, which is an application setting value. In addition, “cloud_service”, which is “id” of a setting item, is associated with “XXX”, which is an application setting value.

Hereinafter, a detailed description is given of an operation performed by the information processing system 1 according to the first embodiment.

For example, a developer of the application 71 changes application settings via the application setting screen displayed on the terminal 32 as indicated in a sequence diagram of FIGS. 10A, 10B and 11. FIGS. 10A, 10B and 11 are a sequence diagram illustrating an example operation of setting an application.

At S11, the terminal 32 accepts a developer instruction that requests display of an application setting list screen through the display/input unit 61. At S12, the display/input unit 61 requests the screen generator 64 to generate the application settings list screen. At S13 and S14, the screen generator 64 acquires HTML data of the application settings list screen from the application 71 of the Web service provision apparatus 22 via the communication unit 62.

At S15, the screen generator 64 generates the application setting list screen based on the acquired HTML data. At S16, the screen generator 64 requests the script analyzer 63 to execute a script contained in the acquired HTML data. The script analyzer 63 executes the script contained in the HTML data to perform subsequent processing.

At S17 and S18, the script analyzer 63 requests the application data manager 72 of the Web service provision apparatus 22 for an application setting value ID list. The application data manager 72 reads out each application setting value ID from the application setting value information as illustrated in FIG. 6 stored in the application setting value information storage 74 to generate the application setting value ID list as illustrated in FIG. 12. FIG. 12 is an illustration of an example configuration of the application setting value ID list.

The script analyzer 63 acquires the application setting value ID list as illustrated in FIG. 12. At S19, the script analyzer 63 generates an application setting list screen 1000 as illustrated in FIG. 13 based on the acquired application setting value ID list.

FIG. 13 is an illustration of an example of the application setting list screen 1000. The application setting list screen 1000 includes keys 1002 a to 1002 c. A uniform resource locater (URL) for transitioning to each application setting screen is set to each of the keys 1002 a to 1002 c. This URL for transitioning to each application setting screen includes the application setting value ID. For example, an URL of “http://example.com/settings/879QOWI0” is allocated to the key 1002 a corresponding to Application A. “879QOWI0” contained in this URL is the application setting value ID.

At S20, the display/input unit 61 of the terminal 32 accepts a developer instruction that requests display of the application setting screen according to a user selection of at least one of the keys 1002 on the application setting list screen 1000. At S21, the display/input unit 61 of the terminal 32 requests the screen generator 64 to generate the application settings screen while specifying the URL that is set to the key 1002 selected by the developer.

At S22 and S23, the screen generator 64 acquires an application setting screen template (HTML data) as illustrated in FIG. 14 from the application 71 of the Web service provision apparatus 22. FIG. 14 is an illustration of an example configuration of the application setting screen template. As illustrated in FIG. 14, the application setting screen template is HTML data of a screen on which an area displaying a setting item and a save key are present, the screen not including information specific to each application 71.

At S24, the screen generator 64 generates the application setting screen template based on the acquired HTML data. At S25, the screen generator 64 requests the script analyzer 63 to execute a script contained in the acquired HTML data. The script analyzer 63 executes the script contained in the HTML data to perform subsequent processing.

At S26 and S27, the script analyzer 63 requests the application data manager 72 of the Web service provision apparatus 22 for application setting screen metadata. More specifically, the script analyzer 63 requests acquisition of the application setting screen metadata by using the application setting value ID of the URL that is set to the key 1002 selected by the developer as a key.

The application data manager 72 acquires the application setting value information from the application setting value information storage 74 by using the application setting value ID as a key. Next, the application data manager 72 acquires application information from the application information storage 73 by using an application ID contained in the acquired application setting value information as a key. The application data manager 72 acquires application setting screen metadata contained in the acquired application information, and sends the application setting screen metadata to the script analyzer 63 of the terminal 32.

At S28 and S29, the script analyzer 63 requests the application data manager 72 of the Web service provision apparatus 22 for an application setting value. More specifically, the script analyzer 63 requests acquisition of the application setting value by using the application setting value ID of the URL that is set to the key 1002 selected by the developer as a key.

The application data manager 72 acquires the application setting value information from the application setting value information storage 74 by using the application setting value ID as a key. The application data manager 72 acquires the application setting value included in the acquired application setting value information, and sends the application setting value to the script analyzer 63 of the terminal 32. It should be noted that the application data manager 72 sends a default application setting value for the first time.

At S30, the script analyzer 63 generates a setting item part in the application setting screen based on the application setting screen metadata and the application setting value to fill in the “area displaying a setting item” in the application setting screen template illustrated in FIG. 14. More specifically, at S30, the script analyzer 63 determines an HTML element to be used based on mapping information as illustrated in FIG. 15. FIG. 15 is an illustration of an example configuration of the mapping information associating a type of setting item with HTML data. It should be noted that the mapping information is included in a script that the application setting screen template has.

With the operation described so far, the terminal 32 generates HTML data of the application setting screen 1100 as illustrated in FIG. 16. The application setting screen 1100 illustrated in FIG. 16 is based on the application setting screen metadata of FIGS. 7A and 7B and the application setting value of FIG. 9.

At S31, the display/input unit 61 of the terminal 32 accepts a developer instruction that requests a change of the application setting value through the application setting screen 1100. At S32, the display/input unit 61 of the terminal 32 notifies the screen generator 64 of the change of the application setting value. At S33, the screen generator 64 requests the script analyzer 63 to execute a script corresponding to the application setting screen 1100. At S34, the script analyzer 63 determines whether the changed application setting value is appropriate using the appropriateness check information included in the application setting screen metadata of FIGS. 7A and 7B.

In a case in which there is a need to notify a result of the appropriateness check, for example, in a case in which a result of the appropriateness check performed at S34 indicates that the changed application setting value include an inappropriate application setting value, the script analyzer 63 generates a message indicating the result of the appropriateness check at S35. Further, the script analyzer 63 causes the display/input unit 61 of the terminal 32 to display the generated message.

At S36, the display/input unit 61 of the terminal 32 accepts a developer selection of a save key on the application setting screen 1100. At S37, the display/input unit 61 of the terminal 32 notifies the screen generator 64 of the selection of the save key.

At S38, the screen generator 64 requests the script analyzer 63 to execute a script corresponding to the selection of the save key. At S39 and S40, the script analyzer 63 requests the application data manager 72 of the Web service provision apparatus 22 to update the application setting value to the application setting value changed according to the developer instruction given through the application setting screen 1100. In response to the request from the terminal 32 for updating the application setting value, the application data manager 72 updates the application setting value in the application setting value information storage 74.

This enables a developer of the application 71 to update an application setting value through the application setting screen 1100 generated based on the application setting screen metadata. Further, the developer can dynamically recognize an appropriateness of the changed application setting value. Furthermore, the developer can change a setting item on the application setting screen in a simple manner by editing the application setting screen metadata.

Accordingly, the developer can prepare the application setting screen 1100 in a simple manner depending on a setting item or an application setting value that is to be set to an application screen described later and check an appropriateness of the application setting values. This improves efficiency in developing a web application.

FIG. 17 is a sequence diagram illustrating steps in an operation of using the application 71 through an application screen of the application 71 displayed on the image forming apparatus 12.

At S51, the image forming apparatus 12 accepts a user instruction that requests display of an application screen through the display/input unit 51. For example, the application setting value ID is included in a path or a query parameter of a URL of the application screen of “app 1” as a target of the request for displaying the application screen. The URL of the application screen is, for example, “http://example.com/apps/appl.html?appdata_id=879QOWI0”. “879QOWI0” contained in this URL is the application setting value ID.

At S52, the display/input unit 51 requests the screen generator 54 to generate the application screen of “app 1” while specifying the application setting value ID. At S53 and S54, the screen generator 54 acquires, via the communication unit 52, HTML data of the application screen of “app 1” from the application 71 of the Web service provision apparatus 22.

At S55, the screen generator 54 generates the application screen based on the acquired HTML data. At S56, the screen generator 54 requests the script analyzer 53 to execute a script contained in the acquired HTML data. The script analyzer 53 executes the script contained in the HTML data to perform subsequent processing.

At S57 and S58, the script analyzer 53 requests the application data manager 72 of the Web service provision apparatus 22 for an application setting value. The application data manager 72 reads out the application setting value as illustrated in FIG. 9 from the application setting value information storage 74 by using the application setting value ID as a key. Further, the application data manager 72 sends the read-out application setting value to the script analyzer 53 of the image forming apparatus 12.

At S59, the script analyzer 53 fills in a user interface (UI) based on the acquired application setting value on an application screen 1200 as illustrated in FIG. 18. FIG. 18 is an illustration of an example of an application screen. FIG. 18 illustrates the application screen 1200 in which an UI is filled in based on the application setting value of FIG. 9. FIG. 18 illustrates an example of the application screen 1200 on which a “FILE NAME” field reflects (QUOTE) as a file name initial value (default_filename) included in the application setting value.

At S60, the script analyzer 53 retains one or more parameters from among the application setting value as illustrated in FIG. 9 on a memory, the parameter being used for other than the UI. In an example of the application setting value as illustrated in FIG. 9, a date format (date_format) and a cloud service (cloud_service) are retained on a memory.

It should be noted that the date format (date_format) is a parameter used for enabling the “FILE NAME” field to reflect a date as illustrated in the application screen 1200 of FIG. 19 in response to a selection of “TODAY” key on the application screen 1200 of FIG. 18. FIG. 19 is an illustration of an example of an application screen on which a date is reflected in the “FILE NAME” field. It should be noted that, FIG. 19 illustrates an example in which, a character string indicating a today's date is generated and attached to the file name on the application screen 1200 according to yyyy-dd-mm as the date format (date_format) included in the application setting value.

Further, the cloud service (cloud_service) is used when scanning a document in response a user selection of a “START” key on the application screen 1200 and uploading a file of the scanned document. In a case in which “XXX” is set to the cloud service, the file obtained by scanning a document is sent to a URL “http://example.com/upload?service=xxx”, for example.

Although FIGS. 7A and 7B illustrate an example of the application setting screen metadata for a cloud scanning service, any other suitable service may be provided. FIGS. 20A to 20C are an illustration of an example configuration of application setting screen metadata for a Scan to Email service. In addition, FIG. 21 is an illustration of an example configuration of application setting screen metadata for a cloud printing service.

An application setting screen as illustrated in FIG. 22 is generated based on the application setting screen metadata of FIGS. 20A to 20C. FIG. 22 is an illustration of an example of an application setting screen for the Scan to Email service. The application setting screen of FIG. 22 includes a mail subject, a mail text, and a scan color mode, each being a setting item. The mail subject is a subject of an email for sending a scanned file. The mail text is a text of the email for sending the scanned file. The scan color mode is a scan color mode selected by default.

An application setting screen as illustrated in FIG. 23 is generated based on the application setting screen metadata of FIG. 21. FIG. 23 is an illustration of an example of an application setting screen for the cloud printing service. The application setting screen of FIG. 23 includes a default folder ID, a print color mode, and a check box mail for prohibiting a change of the print color mode, each being a setting item.

The default folder ID is an ID of a folder that is displayed first at the image forming apparatus 12. The print color mode is a print color mode selected by default. Putting a mark in the check box for prohibiting change of print color mode disables a change of the print color mode according to an instruction given from a user of the image forming apparatus 12. For example, when “monochrome” is set to the print color mode as illustrated in FIG. 23 and a mark is put in the check box, a monochrome print is forced.

FIG. 32 is an illustration of an example configuration of application setting screen metadata based on which an application setting screen including a text box that requires input is generated. In FIG. 32, “required: true” as appropriateness information indicates that a field of a single text whose “id” is “userName” requires input. A check box that requires selection can be also generated by using the appropriateness information “required: true” illustrated in FIG. 32.
